Last week, an update notification was sent out for the BlackBerry App World™ storefront v2.1.2.15. If you are running an older OS version on your BlackBerry® smartphone, specifically BlackBerry® Device Software v4.6 and v4.7, your BlackBerry App World icon may have disappeared after installing the update. We have released a fix for this and the new version, BlackBerry App World v2.1.2.19, is available for download at the link below.
